ELECTRIC VAPORIZER.

Specication of Letters Patent.

Patented Jan. 12, 1915.

Application filed April 5, 1912. Serial No. 688,604.

To all lwhom t may concern:

Be it known that I,- FRANK KUHN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain' new and useful Improvements in Electric Vaporizers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vaporizers and more particularly to carbureters for eXplosion engines.

'It is the object of the invention to provide an electric heater or vaporizer which is readily attachable to any of the usual constructions of carbureters or induction conduits for explosion engines and which in itself is a simple and inexpensive construction to manufacture. r

To this end the invention consists in the construction as hereinafter set forth.

In the drawings,-Figure 1 is a longitudinal section through the induction conduit of an explosion engine to which my attachment is applied; Fig. 2 is a perspective view of the attachment; Fig. 3 is a cross section in a plane transverse to Fig. 1; Fig. 4 is a sectional view similar to Fig. l showing a modified construction.

With explosion engines which employ liquid fuel such as gasolene, it is usual to form the carbureter as al separate unit which is attached to the induction conduit of the engine. The attachment is mostgenerally by a ange union, the abutting anges being bolted together with a suitable gasket therebetween. It is desirable in cold weather to assist the vaporization of the oil by preheating, and on account of its instantaneous action, an electric heater is peculiarly adapted for this purpose.

y improvement consists in the arrangement of an electric heater in a member which is insertible in' the induction 4conduit and more particularly in an insulator member to which the naked resistor may be attached.

As shown in Figs. l, 2 and 3, A is the liange end of Ithe induction conduit of an explosion engine and B the correspondingly flanged portion of the carburetor attached to said conduit. C is a member formed of insulating material having an aperture D correspondingto the interior dimension of the conduit A and having its outer contour preferably corresponding to that of the flanges on the members A and B. lThus the member C may be inserted between said flanges and when clamped in position will operate as a gasket. D is the electric resistor which may be a coil of wire or of any other desired shape. The terminal connections E for this resistor pass out through the side of the member C, and as shown in Figs. 2 and 3, these consist of threaded studs having the clamping nuts F, F for attachment tothe resistor and external circuit.

In Fig. 4a modified construction is shown in which a screw-threaded plug Gr of insulating material is detachably inserted into a correspondingly threaded aperture in the wall H of the induction conduit. I are terminal connections passing throughv said plug and J is a resistor attached inner ends of these terminals.

With both constructions, the heater may to theV be readily inserted or removed from the conduit so as to permit of repair or replacement, and in each case the construction is exceedingly simple and inexpensive to manufacture.

What I claim as my invention is:

1. The, combination with an induction conduit having abutting sections, of a comparatively thin open-centered member ar` ranged between the abutting sections, an electric resistor carried by said member, and a terminal connection passing out through' said member.

A2. The combination with an induction conduit having abutting sections, of a comparatively thin open-centered gasket formed of insulating material, an electric resistor arranged within the open center of said gasket, and a terminal to said resistor and gasket.

3. The combination with an induction conduit having abutting iiange sections and clamping means for securing said sections connection attached passing out throu'fl the together, of a comparatively thin open-centered gasket formed ofinsulating material, an electric resistor comprislng a coil of wire arranged Within the open center of said In testimony whereofI aiix my'signature gasket, and terminal connections passing in presence of two witnesses. out through said gasket, the inner ends of FRANK KUHN. said terminals projecting Within the open Witnesses:

5 center of the gasket and being` respectively W. J. BELKNAP,

connected to the ends of said wire. l JAMES P. BARRY.
